Dr Nash was recommended by our pediatrician and we felt that he answered all our questions with utmost clarity and respect. I would definitely return to his office in the future
Dr. Nash spoke to me with respect and like I was capable of understanding everything he said, but he was also great with my 2 year old. the receptionists and nurses were also incredibly nice and friendly with me and with my daughter.
This was our first time at this office with this provider and we had a wonderful experience!
I was impressed how long Dr. Nash was willing to talk with us and answer all of our questions. I did not feel rushed, but we also did not have to wait to be seen. Our appointment was in the morning, but I was still very pleased that we were seen so quickly.
Dr. Nash was by far one of the best doctors I have ever seen. He took plenty of time with us. Was very thorough in his explanations.

Not only was Dr. Nash wonderful, but the entire staff was knowledgeable, caring and very professional.
I was so impressed with the amount of time that Dr. Nash spent w my daughter and how thorough he was in explaining to the both of us how he was going to treat her and what we needed to do to assist in the treatment and what to expect. He showed interest and compassion and made myself and my daughter feel at ease and confident that he was dedicated to treating her particular situation.

We have finally found a doctor that knows what is truly going on with our daughter and her allergies, reactions, and eczema. He is undoubtedly helping my daughter and making her life so much better!
Provider did not seem concerned about the patient's concerns. There was no clear follow up plan.
Really great experience!!
dr Nash has always provided excellent care.
made my daughter very feel comfortable
Dr. Nash is a wonderful doctor who spent a lot of time explaining care plans and had a great way with my son. He helped me to understand his allergies and how to manage his care. I have recommended him to everyone and my niece is now also a patient with him based on my recommendation.
Dr. Nash was wonderful!! I was very impressed with the effort he made to connect with my son. He took the time to explain the tests and make him (and me) feel comfortable.
we felt like both Dr Nash as well as Nurse Jamie? were very concerned for our daughter and took special care of her and worked well to keep her fears minimal. I feel that they both went above and beyond to make our first and hopefully last experience with allergy testing a lot easier than it could of. they both went out of their way to build a relationship with my daughter to out her at ease. I give them both an A+++++++
I was very impressed with Dr. Nash.

Fantastic experience . Dr Nash made all of us very comfortable and eased our concerns about our son.
Dr. Nash possessed a confidence in his abilities and in his knowledge of what were were dealing with. This was very comforting to me.
First visit - very impressed and pleased with the doctor!
We have seen Dr. Nash for years and truly feel his is one of the best doctors we have ever seen. I wholeheartedly recommend him regularly to others. We are always extremely pleased with his care and his demeanor. We think he is super smart and competent but he is able to make common sense decisions that relate to the individual child. I think that is not always easy to find with physicians.
Changing our allergist to Dr. Nash has been life changing! My little girl is doing so much better! We are undoubtedly so happy we found Dr. Nash and his nurse Tammy! Thank you!!!!!!
Dr. Nash was very polite and directed lots of questions towards my son, not just me. i appreciated that Dr. Nash included my son in the conversations.
Dr. Nash is fantastic. I have referred him multiple times to friends and family members. He is open, honest, courteous, and takes action as needed. He is understanding a flexible and truly listens to his patients/parents. Couldn't ask for a better doctor for my son.
He is a nice doctor and my son love him a lot and we joy see him
Dr. Nash is excellent and we recommend him to everyone.
Dr. Nash, and all of the nurses and aids at Children's are amazing. We've had to see several doc in varying branches of Children's lately and they've all been wonderful. Dr. Cassidy, Dr. Mitchell and Dr. Nash are all amazing. We are thankful to live in a city with such incredible medical professionals.
we were very pleased with Dr. Nash and the entire staff.
This was the first visit we had to this MD and to the building. I felt all the staff were repectful and overall had a wonderful experience.
DR. NASH IS EXCELLENT. HE IS VERY THOUROUGH AND KNOWLEDGABLE. HE EXPLAINED EVERYTHING AND CHECKED FOR UNDERSTANDING/ALLOWED ME TO ASK QUESTIONS. I WAS VERY IMPRESSED WHEN I HAD TO CALL THE ALLERGIST ON CALL AND THEY TOOK THE THE TIME TO PROVIDE ME WITH ENOUGH INFORMATION TO FEEL CONFIDENT IN MY CHILD'S TREATMENT AND DR. NASH FOLLOWED UP LATER THAT DAY. I AM EXTREMELY HAPPY WITH THE CARE. THIS IS A VERY PROFESSIONAL PRACTICE.

Dr. Nash and his staff were wonderful and made me and my daughter very comfortable. I was very pleased with the entire visit.
Very good experience.The doctor explained the results of my daughter's tests,and treatment plan that would be most helpful.
Dr. Nash was concerned about the comfort of our child and putting him at ease, even remembering to call him by his nickname. His notes and medical records are very thorough, and he does an excellent job of explaining our child's condition to us (and to our child) and making sure we are trained to manage it at home. Overall, the protocol is very clear and effective, and the office is well run. Couldn't ask for more! Highly recommended to fellow allergy families!
Dr. Nash is great. He and Dr. Spahr have been amazing in helping to control my daughter's asthma and allergies.
Dr. Nash is the total package; intelligent, perceptive, compassionate, and well-trained. He was able to give us the reassurance we were seeking.

I loved Dr. Nash I would definitely recommend him to anyone looking for an allergist for their child.
The nursing staff are wonderful! the nurse who was doing my child's weight and height was fantastic. she was compastonate with my son and his needs. the nurse who did the stick test was so calm and understanding. Dr Nash was fantastic. he spoke to my son the whole time. I loved everything about this visit.
dr Nash did a great job of speaking to my son, the patient and not just asking me for the answers. his nurse has a great bedside manner
He is excellent in explaining and also very honest and nice with kids
The office was very prompt, no waiting, nurse and doctor clearly explained what would happen on the visit, how long it would take, etc. The nurse was great - my son was nervous and she spent time talking through things with him and setting expectations. For next time, I would like the doctor to listen more before he comments. I was surprised at how many times he interrupted me or jumped to conclusions. Since he was referred to me by my pediatrician, I would have expected a similar experience. In the end, I walked out the office without feeling like I have a plan to care for my son. I turned to my son and said, "You know, I didn't really like the way he (the doctor) spoke to me" and my son looked up at me and said, "Guess what. I didn't like how he talked to me either."
Dr asked if I had any questions or concerns and then answered in way I could understand.
We have been thrilled with Dr. Nash for the past 10 years. We have recommended him to many many people. The best of the best.
Dr. Nash is the best. Recommend him all the time to many people.
Dr. Nash is awesome!!! I have referred him to so many of my friends and they think very highly of him too.
We were there for allergy skin tests. Both dr and the staff did very well explaining the process and answering questions. The children were comfortable and tolerated the tests with minimal upset
This was our first visit with Dr. Nash. we absolutely loved him. Be spoke to us with respect and concern and was friendly and fun with our daughter making her feel comfortable.
